Also please link this functionality with Ctrl+Z and Ctrl+Y, both in the main doc and in the feedback forms.
Please consider to dramatically incrase the priority of this feature.
When working as a moderator, it happens frequently that some text is overwritten or deleted by accident. In such a stressful moment, the absence of "undo" might push several moderators over the edge, so to say. Each moderator will have at least one such experience, which will negatively impact adoption of NWM now and for a long time to come.
At the least, this missing feature will force moderators to work on a seperate word file and copy paste all in the end, which defeats the purpose of NWM and cooperative working.
You won't be notified about changes to this idea.
